Apologies in advance if this is A, old news or B, too dumb for words. I manged once in a few dozen tries, well, thousands. Setting off a bomb as I was triggering a korok to appear. Cut scene didn't trigger. Frame perfect? I'm a klutz so there's no way I can tell if it's repeatable. If it's possible you shave off 6 seconds x 900.

did you step back when you pressed a? ther is a glitch to dupe seeds like that and the cutscene (if it appears) can bug out a bit
